Thermochemical Optimization of Float Glass Composition: Low-Alumina Glass Development

[摘要] Liquidus temperature (TL) was measured for a float-glass-type composition region with 72.7 to 74.0 mass% SiO2, 0.1 to 0.54 mass% Al2O3, 8.0 to 9.0 mass% CaO, 3.0 to 4.0 mass% MgO, and 13.1 to 14.2 mass% Na2O. Crystalline phases were identified at 900?C as cristobalite, wollastonite and devitrite. The primary phases were tridymite and wollastonite. Partial specific TLs were obtained from the data and compared with the literature.
